GS1247 VPA 78 Lango Safe Water Project

Audit Analysis

The Lango Safe Water Project is a Gold Standard cookstove/energy-efficiency project in Uganda with VVB-confirmed additionality and no reported reversals, but it is undermined by 12 cross-document contradictions, an extensive list of corrective actions (7 formal CARs plus roughly 30 additional items), a 0% leakage deduction that conflicts with the PDD's 5%, and a project-specific baseline. The verified ERR of 61,035 tCO₂e for the 2023–24 monitoring period is 1.5% above the claimed 60,139, a reasonable over-delivery, but the absence of a lifetime ex-ante figure and the volume of unresolved documentation issues limit confidence in the credit's robustness.

Project Description

Red Flags

• ⚠Twelve contradictions across documents, including conflicting leakage justifications ('quantified' vs 'deemed negligible'), conflicting fNRB methods ('local field' vs 'national default'), and conflicting additionality verification outcomes (true in 2024 VR vs false in an undated VR).
• ⚠Seven formal Corrective Action Requests plus approximately 30 additional corrective items covering missing ER calculations, inconsistent breakdown-day records, incorrect table values, outdated methodology version (v1.0 vs required v3.0), and missing ODA declarations.
• ⚠Leakage deduction reduced from 5% in the PDD to 0% in the 2024 verification report, with the justification shifting from 'quantified' to 'deemed negligible' between the monitoring and verification reports.
• ⚠Sector classification in the registry record reads 'industrial' while the project is explicitly a domestic energy-efficiency (cookstove) project, raising a data-integrity question.
• ⚠FPIC status is contradictory: the 2023 monitoring report states it was not conducted, while the 2025 validation report states it was conducted.
